<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>Help parsing or adding <em>trailers</em> lines, that look similar to RFC 822 e-mail
headers, at the end of the otherwise free-form part of a commit
message.</p>
</div>
<div class="paragraph">
<p>This command reads some patches or commit messages from either the
&lt;file&gt; arguments or the standard input if no &lt;file&gt; is specified. If
<code>--parse</code> is specified, the output consists of the parsed trailers.</p>
</div>
<div class="paragraph">
<p>Otherwise, this command applies the arguments passed using the
<code>--trailer</code> option, if any, to the commit message part of each input
file. The result is emitted on the standard output.</p>
</div>
<div class="paragraph">
<p>Some configuration variables control the way the <code>--trailer</code> arguments
are applied to each commit message and the way any existing trailer in
the commit message is changed. They also make it possible to
automatically add some trailers.</p>
</div>
<div class="paragraph">
<p>By default, a <em>&lt;token&gt;=&lt;value&gt;</em> or <em>&lt;token&gt;:&lt;value&gt;</em> argument given
using <code>--trailer</code> will be appended after the existing trailers only if
the last trailer has a different (&lt;token&gt;, &lt;value&gt;) pair (or if there
is no existing trailer). The &lt;token&gt; and &lt;value&gt; parts will be trimmed
to remove starting and trailing whitespace, and the resulting trimmed
&lt;token&gt; and &lt;value&gt; will appear in the message like this:</p>
</div>
<div class="listingblock">
<div class="content">
<pre>token: value</pre>
</div>
</div>
<div class="paragraph">
<p>This means that the trimmed &lt;token&gt; and &lt;value&gt; will be separated by
<code>': '</code> (one colon followed by one space).</p>
</div>
<div class="paragraph">
<p>By default the new trailer will appear at the end of all the existing
trailers. If there is no existing trailer, the new trailer will appear
after the commit message part of the output, and, if there is no line
with only spaces at the end of the commit message part, one blank line
will be added before the new trailer.</p>
</div>
<div class="paragraph">
<p>Existing trailers are extracted from the input message by looking for
a group of one or more lines that (i) is all trailers, or (ii) contains at
least one Git-generated or user-configured trailer and consists of at
least 25% trailers.
The group must be preceded by one or more empty (or whitespace-only) lines.
The group must either be at the end of the message or be the last
non-whitespace lines before a line that starts with <em>---</em> (followed by a
space or the end of the line). Such three minus signs start the patch
part of the message. See also <code>--no-divider</code> below.</p>
</div>
<div class="paragraph">
<p>When reading trailers, there can be no whitespace before or inside the
token, but any number of regular space and tab characters are allowed
between the token and the separator. There can be whitespaces before,
inside or after the value. The value may be split over multiple lines
with each subsequent line starting with at least one whitespace, like
the "folding" in RFC 822.</p>
</div>
<div class="paragraph">
<p>Note that <em>trailers</em> do not follow and are not intended to follow many
rules for RFC 822 headers. For example they do not follow
the encoding rules and probably many other rules.</p>

<div class="dlist">
<dl>
<dt class="hdlist1">trailer.separators</dt>
<dd>
<p>This option tells which characters are recognized as trailer
separators. By default only <em>:</em> is recognized as a trailer
separator, except that <em>=</em> is always accepted on the command
line for compatibility with other git commands.</p>
<div class="paragraph">
<p>The first character given by this option will be the default character
used when another separator is not specified in the config for this
trailer.</p>
</div>
<div class="paragraph">
<p>For example, if the value for this option is "%=$", then only lines
using the format <em>&lt;token&gt;&lt;sep&gt;&lt;value&gt;</em> with &lt;sep&gt; containing <em>%</em>, <em>=</em>
or <em>$</em> and then spaces will be considered trailers. And <em>%</em> will be
the default separator used, so by default trailers will appear like:
<em>&lt;token&gt;% &lt;value&gt;</em> (one percent sign and one space will appear between
the token and the value).</p>
</div>
</dd>
<dt class="hdlist1">trailer.where</dt>
<dd>
<p>This option tells where a new trailer will be added.</p>
<div class="paragraph">
<p>This can be <code>end</code>, which is the default, <code>start</code>, <code>after</code> or <code>before</code>.</p>
</div>
<div class="paragraph">
<p>If it is <code>end</code>, then each new trailer will appear at the end of the
existing trailers.</p>

<div class="paragraph">
<p>If it is <code>start</code>, then each new trailer will appear at the start,
instead of the end, of the existing trailers.</p>
</div>
<div class="paragraph">
<p>If it is <code>after</code>, then each new trailer will appear just after the
last trailer with the same &lt;token&gt;.</p>
</div>
<div class="paragraph">
<p>If it is <code>before</code>, then each new trailer will appear just before the
first trailer with the same &lt;token&gt;.</p>
</div>
</dd>
<dt class="hdlist1">trailer.ifexists</dt>
<dd>
<p>This option makes it possible to choose what action will be
performed when there is already at least one trailer with the
same &lt;token&gt; in the message.</p>
<div class="paragraph">
<p>The valid values for this option are: <code>addIfDifferentNeighbor</code> (this
is the default), <code>addIfDifferent</code>, <code>add</code>, <code>replace</code> or <code>doNothing</code>.</p>
</div>
<div class="paragraph">
<p>With <code>addIfDifferentNeighbor</code>, a new trailer will be added only if no
trailer with the same (&lt;token&gt;, &lt;value&gt;) pair is above or below the line
where the new trailer will be added.</p>
</div>
<div class="paragraph">
<p>With <code>addIfDifferent</code>, a new trailer will be added only if no trailer
with the same (&lt;token&gt;, &lt;value&gt;) pair is already in the message.</p>
</div>
<div class="paragraph">
<p>With <code>add</code>, a new trailer will be added, even if some trailers with
the same (&lt;token&gt;, &lt;value&gt;) pair are already in the message.</p>
</div>
<div class="paragraph">
<p>With <code>replace</code>, an existing trailer with the same &lt;token&gt; will be
deleted and the new trailer will be added. The deleted trailer will be
the closest one (with the same &lt;token&gt;) to the place where the new one
will be added.</p>
</div>
<div class="paragraph">
<p>With <code>doNothing</code>, nothing will be done; that is no new trailer will be
added if there is already one with the same &lt;token&gt; in the message.</p>
</div>
</dd>
<dt class="hdlist1">trailer.ifmissing</dt>
<dd>
<p>This option makes it possible to choose what action will be
performed when there is not yet any trailer with the same
&lt;token&gt; in the message.</p>
<div class="paragraph">
<p>The valid values for this option are: <code>add</code> (this is the default) and

</dd>
<dt class="hdlist1">trailer.&lt;token&gt;.key</dt>
<dd>
<p>This <code>key</code> will be used instead of &lt;token&gt; in the trailer. At
the end of this key, a separator can appear and then some
space characters. By default the only valid separator is <em>:</em>,
but this can be changed using the <code>trailer.separators</code> config
variable.</p>
<div class="paragraph">
<p>If there is a separator, then the key will be used instead of both the
&lt;token&gt; and the default separator when adding the trailer.</p>
</div>
</dd>
<dt class="hdlist1">trailer.&lt;token&gt;.where</dt>
<dd>
<p>This option takes the same values as the <em>trailer.where</em>
configuration variable and it overrides what is specified by
that option for trailers with the specified &lt;token&gt;.</p>
</dd>
<dt class="hdlist1">trailer.&lt;token&gt;.ifexists</dt>
<dd>
<p>This option takes the same values as the <em>trailer.ifexists</em>
configuration variable and it overrides what is specified by
that option for trailers with the specified &lt;token&gt;.</p>
</dd>
<dt class="hdlist1">trailer.&lt;token&gt;.ifmissing</dt>
<dd>
<p>This option takes the same values as the <em>trailer.ifmissing</em>
configuration variable and it overrides what is specified by
that option for trailers with the specified &lt;token&gt;.</p>
</dd>
<dt class="hdlist1">trailer.&lt;token&gt;.command</dt>
<dd>
<p>This option behaves in the same way as <em>trailer.&lt;token&gt;.cmd</em>, except
that it doesn&#8217;t pass anything as argument to the specified command.
Instead the first occurrence of substring $ARG is replaced by the
value that would be passed as argument.</p>
<div class="paragraph">
<p>The <em>trailer.&lt;token&gt;.command</em> option has been deprecated in favor of
<em>trailer.&lt;token&gt;.cmd</em> due to the fact that $ARG in the user&#8217;s command is
only replaced once and that the original way of replacing $ARG is not safe.</p>
</div>
<div class="paragraph">
<p>When both <em>trailer.&lt;token&gt;.cmd</em> and <em>trailer.&lt;token&gt;.command</em> are given
for the same &lt;token&gt;, <em>trailer.&lt;token&gt;.cmd</em> is used and
<em>trailer.&lt;token&gt;.command</em> is ignored.</p>
</div>
</dd>
<dt class="hdlist1">trailer.&lt;token&gt;.cmd</dt>
<dd>
<p>This option can be used to specify a shell command that will be called:
once to automatically add a trailer with the specified &lt;token&gt;, and then
each time a <em>--trailer &lt;token&gt;=&lt;value&gt;</em> argument to modify the &lt;value&gt; of
the trailer that this option would produce.</p>
<div class="paragraph">
<p>When the specified command is first called to add a trailer
with the specified &lt;token&gt;, the behavior is as if a special
<em>--trailer &lt;token&gt;=&lt;value&gt;</em> argument was added at the beginning
of the "git interpret-trailers" command, where &lt;value&gt;
is taken to be the standard output of the command with any
leading and trailing whitespace trimmed off.</p>
</div>
<div class="paragraph">
<p>If some <em>--trailer &lt;token&gt;=&lt;value&gt;</em> arguments are also passed
on the command line, the command is called again once for each
of these arguments with the same &lt;token&gt;. And the &lt;value&gt; part
of these arguments, if any, will be passed to the command as its
first argument. This way the command can produce a &lt;value&gt; computed
from the &lt;value&gt; passed in the <em>--trailer &lt;token&gt;=&lt;value&gt;</em> argument.</p>
